Specification of `Letters Patent.

luatented Dec. 218,

Application led September Il, MM5. Serial No. 48,957.

T all whom it mcg/concern Be it known that l, JOHN C. Donnell, .a subjiect of Austria-Hungary, residingr at Detroit, in the county of l/Vayne and State of Michigan, have invented certain new and useful limprovertiente in Pencils and Sharpeners, of which the following is a specification, reference beingr had therein to the accompanying drawings.

This invention relates to pencils, and the primary object of my invention is to pro- `vide a lead or graphite holder wherein iZS 4,means are combined for adjusting the lead relative to the holder and sharpening or scraping the end of the lead, when in a re- "iracted position., to provide the same with a a point which may be used when the lead is extended relative to the holder.

Another object of ray-invention is to provide a lead'or. graphite holder with perinanent concealed sharpening or scraping devices which can be easily and quickly brought into action to sharpen or scrape a piece of lead or graphite within the holder by simply rotating a portion of the holder.

.ei further object of my invention is to accomplish the above result by a durable inechanical construction that will be hereinafter specifically described and then claimed, and reference will now be had to the drawing, vvhereinl Figure 1 is an enlarged longitudinal sectional. view ot a pencil in accordance with niy invention; Fig. 2 is an enlarged longitudinal sectional view of the writine,` end of the pencil, showing' the lead or graphite' in `a retracted position to be sharpened or scraped; Fig. 3 is a cross sectional view taken on the line IIL-lll of Fig. 2; Fig.' -t is a similar view taken on the line lil-lV? of Fig. 1; Fig. 5 is a similar view taken on the line V-V oi' Fig. l; Fig. 6 is a similar view taken on the line lll-*VI of' Fig. 1; and Fig'. 7 is a, similar view taken on the line Vil-VH of Fig. 1.

in exterior appearance the pencil coniprises a. point section 1, a hand section 2., a

vlead retracting section 3, and a lead extendjungy section i. All these sections are cylindrical and the sections 3 and i may be knurled to facilitate rotating the same. The lead extendingsection il has an inner end wall 5 provided with a clearance tube 6 and adjacent the wallA 5 is a collar 7 integral with the tube 6. Between the wall 5 and the collar 7 is a cylindrical head 8, which as shown in Fig. 7, is split or slitted as at 9, whereby the head may be s} rung over the collar T to loosely engage the clearance tube 6. The head 8 is exteriorly screwthreaded and is mounted in one end of the lead rctractinp; section 3.

The inner end of the clearance tube 6 is out and bent to provide an inwardly projecting .lug 10, and this lug extends into a longitudinal slot 11 provided therefor in a nut tube 12 slidable in the clearance tube 6. By reason of the lug 1G extending' into the slot 11, the tubes 6 and lf2 are arranged 'for rotative continuity when the lead extending section 4- is rotated. rlhe inner end of the nut tube 12 terminates in a nut portion 13 in screwthreaded .engagement with a screw i4 disposed longitudinally of thenut tube 12.

The inner end of the lead reti-acting' section 3 is provided with an exteriorly screwthreaded sleeve 15 tree to revolve upon the clearance tube (3. The sleeve 15 has a longitudinal slot 1G and is in screwthreadcd engagement with an end of an inner barrel 1T. This barrel is slidable longitudinally of an outer barrel 18 fixed by a pin 19 in the hand section The outer barrel has a longitudinal slot 20, and into this slot extends a pin 21 carried by the inner barrel 17, said pin preventing,r the inner barrel 17 from rotating relative to the outer barrel 18.

Screwed into the end of the hand section 2 is a bushing 22 in which the sleeve 15 rcvolves, and said hand section 2 is screwed on a cylindrical bearing` Q3 supporting a tubular lead or graphite holder 24. The holder Qel long/ritudinallvv alines with the nut tube 12 and said holder is adapted to contain a piece of lead or graphite Q5 having the inner end thereof engaged by the screw lll. rl`he inner end of the holder 2li has a head 2G and said head and the nut portion i3 of the nut tube l2 have annular grooves 2'? for stirrups 2S 'forming' part of a coupling ineinber Z9, said coupling member retaining the holder 2i and the nut tube 1.2 in spaced relation, yet allowing the nut tube to freely revolve relative to the holder 24. The stirrups can be ea. ily placed in the annular grooves 27 and to retain said stirrups therein7 the couplingmember 29 has a pin 30. Une end of the pin extends into a longitudinal groove 31 provided therefor in a screw 14, aid groove having closed ends 1w whereby the screw cannot become accidentally displaced relative to the pin 30. The

pin lf3 also prevents a rotative movementof the screw relative to the nut tube 12 and in order that said pin can be easily installed, 1t has an intermediate nut portion 32. The

pin 30 also holds a finger 33 on the coupling the sleeve 15 of the lead retracting Section4 3 and the coupling member 29. The inner barrel 17 has diametrically opposed Walls thereof cut away, as at 34, to-.

reduce the weight of said barrel and the remaining portions ot' said barrel are pro,

vided with inwardly projecting arms 35 engaging the head 26er' the holder 24. The holder 24 has a longitudinal groove 8G and extending into said groove is a pin 37, car-` ried by the bearing 23. A reduced portion of the bearing 23 supports a head 38 and a terr-ole 39, the former being srewed in the point section l of the pencil. Abutting the. lierrule S9 are the semi-cylindrical portions of opposed sharpeners 0r Scrapers 4-1 wh: h are held in position b pins 4-2, carried by the point section 1 anc 'engaging the semi-'cylindrical portions 40 of the Sharpeners or Scrapers. The Sharpeners or Scrapers are resilient and have splitted ends 4,3 beveled, as at 44, and normally held in a retracted position by a spherical or globular expanding member on the holder 24.

The writing end of the pencil terminates in a conical portion 46 of the point section l, said conical portion serving as a guide tor the reciprocable holder 24; In order i that the lead or graphite 25 will not become accidentally displaced relative to said holder, the outer endof the holder is slitted, as at 47 to t'rictionally engage the lead` or graphite.

In operation, l will first assume that the pencil is in position to be used and that it is desired to retract the holder 24 and the lead or graphite 25 thereof'. whereby the pencil can be carried in the pocket withopt danger oi the lead or graphite point being broken. To retract the holder 24, the lead rotracting section 3 is rotated and as the sleeve lris revolved. the inner barrel 17 is shifted'inwardly andthrough thc medium of the arms 35 engaging the head 26, the

presents suiiicient lead or graphite at thev outer end of the holderwhereby it may be sharpened or scraped. The adjustment of the leador graphite having been accom-v plished, the lead or holder retracting section 3 is now rotated until the inner barrel.17 has been retracted as far 'as possible. During' this movement, the nut tube 12 slides in the clearance tube 6 and the coupling mem- 'ber 29 is prevented from. shifting relative to the n'ut tube 12 by reason of the finger 33 extending into the 'slot 16 of the-sleeve 15. sthe holder 24 is retracted, the expanding memberfl releases the scrapersl, asbest shown in Fig; 2, thereby placingy the sharpening or scraping edges of the Scrapers in Iengagement with the lead or graphite 25.

Now, by rotating the hand section 2 the A holder 24 is revolvedand' in consequence of this movement the end of 'the lead" or gran'phite is scraped against and sharpened by holder is moved inwardly, carrying with it the lead or graphite This is accom,v plished by two or three revolutions ot' the lead retracting section 3 which are sullicient to withdraw the point ot the lead or graphite. Assuming again that the pencil has been used andthe lead or graphite ha'sdiecoinc dull and requires'isharpening. "The lead extending section 4 is uo'w rotated and a rotary movement in'lparted to the nut tithe 12, which forces the screw 14' outwardly. thereby pushing the lead or graphite 25 outwardly in the holder 24. 'l` his operation the beveled edges of the Scrapers. Restoring the-inner barrel 17 to a osition intermediate the ends of the hanf section 2 expands the Scrapers 41 and by further shifting the inner barrel 17 the holder 24 emerges from the conical end 46 of the pencil and presents a"sharpened lead or graphite point tor-Writing purposes. l

A Spanner Wrench can be used Afor. as-

sembling certain elements ofthe pene-i1, and

it is thought that th'e operation and utility of the same will be apparent Without further description.
